This invention relates to new and useful 4iniprovements in fuel burnerdevices.

One object of the invention is to providea burner especially adapted tobe used in `conjunction with an air box and adapted to use various kindsof fuel. n

A further object of the invention is to provide a burner including aconicalburner barrel co-acting with an air'deector in taking air from anair box, whereby an intense flame having high heatingqualities isproduced. Another object of the invention is to provide yan improvedsleeve mounting,

A construction designed to carry out kthe invention will bel hereinafterdescribedl together with other features of the invention.

The invention will be more readily understoodfrom a reading of thefollowing specification and by reference to the accompanying drawings inwhich an example of the invention is shown, and wherein:

- Fig. 1 is a vertical sectional view of the front of a furnace fire boxshowing a burner constructed in accordance with the invention -mountedtherein, y

- Fig. 2 is a front elevation of the same,4

Fig. 3 is a View similar to Figl showing the burner mounted for use inconnection with a forced draft equipment, and

Fig. 4 is a similar view showing a combination where either forced orinduced draft may be used. f

In the drawings the numeral designates a metal barrel, cylindrical atits rear or outer end and frusto-conical at its inner or front end fromwhich the flame is projected. The barrel is designed to be embedded inthe fire opening C of the furnace wall A with its rear end and its frontend terminating within the wall. The frustonconical portion of thebarrel causes a concentration of the currents and these are dischargedthrough a bell or outwardly flared lip 11 at the front end of thebarrel.

The wall A of the furnace wall has a flared or frusto-conical port Bflush with the bell and consequently the heated currents which areconcentrated in the frusto-conical portion of the barrehare expanded andspread when passing through the bell and port. This arrangement makesfor ak thorough mixing' of the air and gas currents as well as for anample and hot flame.

An upright metal air box 12 is fitted against the outer face of thefurnace wall A so'as to cover and extend above the-fire opening C.

This box may be of any suitable construction. A transverse draft opening13 is provided in the front wall at the bottom of the box' below thefire opening C. Adamper or draft Idool. 14 is hinged to the top of theopening and is supported by a chain 15 adjustably engaged with a hook16, whereby the damper may be (susgended at different heightsto controlthe An elongated collar 17 is mounted in the the'sleeve within theopening C. The extension of the sleeve into the opening C and the barrelmay be regulated as desired. On the outer or rear end of thev sleeve isfastened the collar 21 of a yoke-shaped bracket 22. The bracket isfastened ina horizontal position by a set screw23 engaging the sleeve.

One arm ofthe bracket has an ear 24, while the other arm of said brackethas a smaller ear 25. A pipe ynipple 26 is mounted in the ear 24 andisscrewed into an elbow 27 at one end and has a union 28 mounted on itsyother end onthe opposite side ofthe ear.

The .elbow is suitably secured to the end of a Y ,flexible conduit orhose 29through which gas is supplied from a suitable source. Anelongated nipple I30 is mount-ed in the ear 25 and is vsuitably attachedat its outer end to a flexible conduit yor hose V31 through which oil orother substitnte fuel issupplied. thekinner end -o f the nipple ismounted a union 32.

One of thefeatures :of the structure is the "quick .change over fromoiiefuel to another and the @fleeting 0f th fliel LSupply @1631@- ioo torsin the 'bracket equipped with unions contiguous to the entrance to thefuel sleeve 19 makes for an expeditious carrying out of this feature.

lVhen gas is being used as a fuel, an elongated fuel tube 33 istelescoped into the sleeve 19. rIhe tube has a snug fit, but is looseenough to be slid freely in the sleeve. An elbow 341 is screwed onto theouter end of the tube and is positioned within the bracket 22. Thiselbow has external screw threads for receiving the nut of the union 28.Thus to disconnect the gas hook-up it is merely necessary to unscrew thenut of the union 28, grasp the. elbow 34 and Withdraw the gas tube fromthe sleeve 19.

The deflector 35 is located in the barrel 10 in advance of the frustoconical end thereof so that the gaseous currents7 resulting from theadmixture of air and gas, are deflected thereby and directed'through thebell 11. The draft currents are concentrated in the frusto conical endof the barrel and mixe-:l with the gaseous currents projected from theburner, thus causing the iaine to spread through the bell 11 and frustoconical port B int-o the re box. This results in a maximum combustionand a hot flame of high heat potentiality.

When the gas supply is suddenly interrupted, as by a break in the mainwhich is quite common in natural gas territories, it is desirable toquickly change to a substitute fuel. If this change can be quicky madevery little drop will occur in the steam Jressure. As hereinbeforestated, by disconnecting the union 28 the gas tube 33 is uncoupled andmay be readily withdrawn from the sleeve 19. A suitable oil tube (notshown) may be inserted in the sleeve 19 and connected with the union 32.

`In 3 the air box 1231s made Without the draft opening 13 and a forceddraft flue 8O is connected to the top of the box, whereby the burner maybe operated under a forced f The door 14 is hinged in this opening andprovided with the chain 15 adjustable on the hook 16. When it is desiredto use a forced draft the door 14 is fastened in its closed position byone or more bolts 83. When it is desired to use an induced ornaturaldraft the damper 82 is closed and the forced draft is cut oil'from the flue 80. By

opened and air supplied to the box through the opening 13.

Various changes in the size and shape of the different parts, as well asmodifications and alterations, may be made within the scope of theappended claims.

What I claim, is:

1. In a fuel burner mounting, the combination with the burner port of afurnace fire box, of a barrel mounted in said port and having one endcontracted and provided with an outwardly flared bell within said port,

the barrel being free from metallic fastenings exterior of the re boxwall, and a plastic lining in which said barrel is embedded andconstituting its sole means of fastening in the fire box. l

2. In a. fuel burner device,v an upright air box having a front wall anda damper controlled air inlet, said box being constructed to be mountedin front of the fire opening of a furnace so that its front wall isspaced al substantial distance from the furnace wall, a fianged collarmounted in the front wall of the air box, a sleeve adjustably mounted inthe collar and extending through the box vinto the furnace, an airdeflector on the inner end of the sleeve, and a burner tube adjustablein the sleeve and having a nozzle coacting with the air deflector.

3. In a fuel burner device, the combination with a furnace wall having afire opening, of an upright rectangular air box extending up the face ofthe furnace wall from the base thereof and enclosing the fire openA ing,said box being self-supporting, the box having an air opening in itslower front wall below the fire opening of the furnace wall, a damperfor closing the box opening, a burner support mounted in the front wallyof the box, and a burner tube mounted in the support and extending intothe fire opening. In testimony whereof I affix my signature.
